Abstract
A study]las been carried out on the acid soluble fraction (hydrosysis at pH 1.5, 3N HCl, 20 % KCl) of organic matter (OM) in the highly calc areous lacustrine sediments of the Jura region, France. Amino acids (A A's) were quantified and determined ninhydrin photometry and HPLC resp ectively. There was a high degree of interference by calcium in both p rocedures. The mechanism of interference is explained and methodology adopted to overcome it, by removal of calcium, are dealt with. The res ults of both methods are compared.
